WHITNEY HOUSTON

Known simply as The Voice, Houston ruled the '80s and '90s pop charts with such hits as "The Greatest Love of All," "How Will I Know" and "I Wanna Dance With Somebody." But the troubled star, whose personal struggles with addiction and tumultuous marriage to Bobby Brown often overshadowed her talent, will best be remembered for her cover of Dolly Parton's "I Will Always Love You" – the mega-selling track from her 1992 film debut in The Bodyguard. Fittingly, it was that Houston classic that played nearly 20 years later during her funeral at her childhood church in Newark, N.J., where the 48-year-old was laid to rest a week after being found dead from accidental drowning in the Beverly Hilton Hotel on February 11.
